There is now review from "people" because there is no section for it and these products are for "research" use only.
They are a good place for products, I have used them for years now and you can find feedback on them for the last 10+ years right here as well.
I'm using their Stane right now , just finished some of their letro and will be using the MT2 for my research next month.
Never a compliant from me anyway...
